Ppp or Std? Need help, been depressed for months

Ive contacted a doctor a couple months ago regarding a weird row of dots that ive gotten from having unprotected sex many months prior. Following the intercourse, i got them a day later, but i experianced no pain while peeing/masterbating/etc. And on top of that they never changed in size or color, nor did they ooze out any liquids or effect my penis at all.
im 17

The doctor i talked to said they could be an infection or yeast infection and that i should use lotrimin, ive been using the cream for s couple days now as prescribed but it seem it hasnt changed. This has really effected my mental health because im afraid that this could effect me later in life.!

Those are PPP’s. They may appear a little more pronounced when your penis is hard like that.

Possible yeast infection, but its really hard to tell, the penis look fine to me. If you do have an infection, it will clear up over time by itself. Give it time, stay clean.
